KURT Tippett's controversial push to join Sydney has taken another twist, with the premier also eyeing his brother, Joel.

West Adelaide coach Andrew Collins - who has helped revive Joel's AFL aspirations - said the Swans were one of three AFL clubs to show strong interest in rookie-listing the key defender at the December 11 draft, along with St Kilda and Carlton.

Providing it is given AFL approval, Sydney is expected to claim key forward Kurt at the pre-season draft on the same day in a four-year deal worth $3.5 million.

In a move which could be seen as trying to further sweeten Kurt, the Swans have spoken to the Bloods several times about Joel - a standout 24-year-old full back who in is first season in the SANFL this year made The Advertiser team of the year.

"I've had quite a few clubs enquire about him because he's a great kid," Collins said of Joel, a former Brisbane rookie who played two games for Gold Coast in 2011.
